Description

La présente invention concerne un équipement de stockage de matériel chirurgical spécialement destiné à être utilisé dans un bloc opératoire chirurgical comprenant une salle d'opération dont les murs sont dépourvus de volumes intérieurs de rangement et un procédé pour la mise en oeuvre de cet équipement. Un tel équipement, qui comprend plusieurs chariots consistant en une étagère rigide adaptée pour recevoir des paniers et un plateau amovibles eten un châssis démontable est connu de DE-A-1 919 896.The present invention relates to a surgical material storage equipment specially intended for use in a surgical operating theater comprising an operating room whose walls are devoid of interior storage volumes and a method for the implementation of this equipment. Such equipment, which comprises several trolleys consisting of a rigid shelf adapted to receive removable baskets and a tray and a removable chassis is known from DE-A-1 919 896.

Suivant un agencement à peu près classique des blocs opératoires il est prévu une zone dite "propre" qui comprend les salles d'opérations elles-mêmes, une anti-chambre de préparation pour les chirurgiens et leurs assistants, éventuellement une chambre d'anesthésie et de réanimation, et une pièce dans laquelle est stocké et manipulé le matériel stérile, dite "stérilisation côté propre" ou "stock stérile", cette pièce communiquant avec une zone dite "stérilisation côté sale" ou "côté lavage" par l'intermédiaire d'un ensemble de désinfection et de stérilisation dont l'entrée se trouve dans la zone sale.According to a more or less conventional arrangement of operating theaters, a so-called "clean" zone is provided which includes the operating rooms themselves, an anti-preparation room for surgeons and their assistants, possibly an anesthesia room and resuscitation, and a room in which sterile equipment is stored and handled, called "clean side sterilization" or "sterile stock", this room communicating with an area called "dirty side sterilization" or "washing side" via '' a disinfection and sterilization set whose entrance is in the dirty area.

Après avoir été stérilisé le matériel est stocké dans la ou les salles d'opérations dont au moins un mur est aménagé à cet effet et comporte des vitrines, armoires, tiroirs, catgutiers, et, éventuellement des guichets traversants.After being sterilized, the equipment is stored in the operating room (s), at least one wall of which is fitted out for this purpose and includes display cases, cupboards, drawers, catgutiers, and possibly through counters.

La nécessité de prévoir des éléments de rangement a conduit à profiter des aménagements en épaisseur sur le ou les murs de la salle d'opérations pour y encastrer également certains appareils tels que le bistouri électrique, le système d'aspiration chirurgien, le négatoscope, etc.The need to provide storage elements has led to taking advantage of the thickness arrangements on the wall or walls of the operating room to also embed certain devices such as the electrosurgical unit, the surgical suction system, the negatoscope, etc. .

Ces éléments de rangement et ces appareils encastrés présentent en conséquence de nombreux recoins et espaces difficilement accessibles dont l'étanchéité au formol n'est pas toujours satisfaisante et dont la désinfection pose toujours des problèmes.These storage elements and these built-in devices consequently have many recesses and spaces that are difficult to access, their formaldehyde tightness is not always satisfactory and whose disinfection always poses problems.

En outre ces aménagements muraux sont compliqués, très longs à installer et grèvent par conséquent lourdement les en frais de construction et d'installation des blocs opératoires.In addition, these wall fittings are complicated, very time-consuming to install and consequently impose a heavy burden on construction and installation costs for operating theaters.

L'invention a pour but de remédier à ces inconvénients en fournissant un équipement spécialement destiné à être utilisé dans un bloc opératoire chirurgical comprenant une salle d'opération dont les murs sont dépourvus de volumes intérieurs de rangement, et un procédé pour la mise en oeuvre de cet équipement, permettant de supprimer les éléments et volumes de rangement en salles d'opérations tout en mettant à portée immédiate du chirurgien les matériels et l'instrumentation dont il a besoin pour les interventions, et de simplifier les manipulations de ces instruments et accessoires après usage et notamment lors de leur désinfection et stérilisation.The object of the invention is to remedy these drawbacks by providing equipment specially intended for use in a surgical operating theater comprising an operating room whose walls are devoid of interior storage volumes, and a method for implementing it. of this equipment, making it possible to remove the elements and volumes of storage in operating rooms while putting within immediate reach of the surgeon the materials and the instrumentation which he needs for the interventions, and to simplify the handling of these instruments and accessories after use and especially during their disinfection and sterilization.

L'équipement suivant l'invention, comprend plusieurs chariots démontables adaptés pour recevoir des paniers et un plateau P, amovibles, un dispositif de montage desdits chariots, un dispositif de démontage desdits chariots et un porte-chariots déplaçable adapté pour recevoir des éléments de plusieurs desdits chariots démontés, dans des positions adjacentes de façon à présenter un encombrement minimal, et au moins un support fixe adapté pour recevoir des paniers.The equipment according to the invention comprises several removable trolleys suitable for receiving removable baskets and a tray P, a device for mounting said trolleys, a device for dismantling said trolleys and a movable trolley carrier suitable for receiving elements from several said disassembled carriages, in adjacent positions so as to have a minimum bulk, and at least one fixed support adapted to receive baskets.

L'invention a également pour objet un procédé pour la mise en oeuvre de l'équipement défini ci-dessus, dans un bloc opératoire chirurgical comportant une salle d'opération dont les murs sont dépourvus de volumes intérieurs de rangement, caractérisé en ce qu'on utilise au moins un chariot démonté et au moins un lot d'instruments et d'accessoires préconditionnés disposé dans un stock stérile situé dans la zone propre du bloc opératoire, et dans lequel, préalablement à l'intervention, on procède au montage d'au moins un chariot sur lequel on charge ledit lot préconditionné, on ramène l'ensemble après l'intervention dans une zone sale, comme connu en soi, on procède au démontage dudit chariot dans cette zone sale, on reconditionne ledit lot d'instruments et on traite simultanément ledit chariot démonté et le lot d'instruments dans un ensemble de désinfection et de stérilisation.The subject of the invention is also a method for implementing the equipment defined above, in a surgical operating theater comprising an operating room whose walls are devoid of interior storage volumes, characterized in that at least one dismounted trolley is used and at least one batch of preconditioned instruments and accessories placed in a sterile stock located in the clean area of the operating theater, and in which, prior to the intervention, the assembly of at least one trolley on which said preconditioned batch is loaded, the assembly is returned after the intervention to a dirty zone, as known per se, the trolley is dismantled in this dirty zone, said batch of instruments is repackaged and said disassembled carriage and the batch of instruments are simultaneously treated in a disinfection and sterilization assembly.

Ce procédé pour la mise en oeuvre de l'équipement est de plus caractérisée en ce qu'on prévoit un poste d'emmagasinage des éléments de chariots démontés, un poste de montage des chariots, un poste d'emmagasinage de lots d'instruments préconditionnés, en stock stérile, situés dans une seule et même zone stérile, un poste de démontage des chariots et un poste de lavage situés dans une seule et même zone dite zone sale, au voisinage d'un ensemble de désinfection et de stérilisation disposé entre ladite zone stérile et la zone sale et isolé de celles-ci de façon connue.This method for implementing the equipment is further characterized in that there is provided a storage station for dismantled cart elements, a cart assembly station, a station for storing batches of preconditioned instruments. , in sterile stock, located in one and the same sterile zone, a car dismantling station and a washing station located in one and the same so-called dirty zone, in the vicinity of a disinfection and sterilization assembly disposed between said sterile area and the dirty and isolated area thereof in a known manner.

On comprend que grâce à l'équipement, et au procédé suivant l'invention on peut éliminer de la salle d'opérations tous les appareils ou installations qui peuvent être rendus mobiles, c'est-à-dire d'une part tous les éléments de rangements: tiroirs, placards, vitrines, catgutiers, ainsi que les guichets remplacés par l'équipement suivant l'invention, et d'autre part le système d'aspiration chirurgien (niche à flacons), le bistouri électrique, et les paillasses éventuelles, seuls restant fixes: le négatoscope, l'éclairage chirurgical et les prises électriques et de gaz médicaux.It is understood that thanks to the equipment, and to the process according to the invention, it is possible to eliminate from the operating room all the apparatus or installations which can be made mobile, that is to say on the one hand all the elements storage: drawers, cupboards, showcases, catgutiers, as well as the counters replaced by the equipment according to the invention, and on the other hand the surgical suction system (niche with bottles), the electrosurgical unit, and any bench-top , only remaining fixed: the X-ray viewer, surgical lighting and electrical and medical gas outlets.

Le négatoscope et les prises pouvant être facilement réalisés étanches, la salle d'opérations est ainsi pratiquement dépourvue de toutes les installations murales utilisées jusqu'à présent, ce qui permet de réaliser la salle avec des murs parfaitement lisses et de ce fait pouvant être très facilement nettoyés et désinfectés.The X-ray viewer and the sockets can be easily waterproofed, so the operating room is practically devoid of of all the wall installations used so far, which allows the room to be made with perfectly smooth walls and therefore can be very easily cleaned and disinfected.

En outre la construction du bloc opératoire et de la salle d'opérations en sont considérablement simplifiés ce qui permet d'abaisser de façon importante le prix de revient global de l'installation.In addition, the construction of the operating theater and the operating room are considerably simplified, which makes it possible to significantly lower the overall cost price of the installation.

La suppression du stockage au niveau de la salle d'opérations entraîne bien entendu la nécessité de préparer le matériel nécessaire à chaque intervention au niveau du stock stérile.The elimination of storage at the level of the operating room naturally leads to the need to prepare the equipment necessary for each intervention at the level of the sterile stock.

En conséquence, avec l'équipement et le procédé suivant l'invention, on préparera à l'avance dans le local d'emmagasinage en stock stérile des paniers adaptés pour être utilisés avec les chariots et contenant des lots de matériel, d'instrumentations et d'accessoires nécessaires pour des interventions déterminées, constituant ainsi des ensembles répertoriés préparés à l'avance et emmagasinés à l'état stérile, prêts à être immédiatement utilisés.Consequently, with the equipment and the method according to the invention, baskets adapted for use with the carts and containing lots of equipment, instrumentations and the like, will be prepared in advance in the sterile storage room. accessories necessary for specific interventions, thus constituting listed assemblies prepared in advance and stored in a sterile state, ready for immediate use.

L'installation suivant l'invention prévoit dans ce but un local situé en zone dite "propre" comportant des éléments spéciaux de support et d'emmagasinage pourvus de moyens identiques à ceux des chariots pour soutenir les paniers garnis et permettant ainsi un emmagasinage en stock stérile des ensembles de paniers répertoriés.The installation according to the invention provides for this purpose a room located in a so-called "clean" area comprising special support and storage elements provided with means identical to those of the carriages to support the packed baskets and thus allowing storage in stock. sterile sets of baskets listed.

En se référant aux Fig. 1 à 5 on a représenté les différents éléments de l'équipement suivant l'invention. Cet équipement comprend un chariot démontable 1, un dispositif 20 de montage et de démontage des chariots, un porte chariots démontés 33 et un support fixe 41.Referring to Figs. 1 to 5 the various elements of the equipment according to the invention have been shown. This equipment comprises a removable carriage 1, a device 20 for mounting and dismounting the carriages, a dismantled carriages carrier 33 and a fixed support 41.

La Fig. 1 montre un chariot 1 conçu et adapté spécialement pour être utilisé dans un bloc opératoire chirurgical, comprenant une salle d'opération dont les murs sont dépourvus de volumes intérieurs de rangement, ce chariot étant constitué par deux éléments d'extrémité identiques 2 comprenant chacun deux montants parallèles 3 reliés entre eux par des traverses espacées 4 parallèles constituant des supports pour des paniers 5 comme on le décrira dans la suite.Fig. 1 shows a trolley 1 designed and specially adapted for use in a surgical operating theater, comprising an operating room whose walls are devoid of interior storage volumes, this trolley consisting of two identical end elements 2 each comprising two parallel uprights 3 interconnected by spaced transverse crosspieces 4 constituting supports for baskets 5 as will be described below.

Les montants 3 des éléments d'extrémité, qui sont de façon commode constitués par des tubes creux en acier inoxydable de section rectangulaire et fermés à leurs extrémités, comportent sur leurs faces en regard, au voisinage de leurs extrémités supérieures et inférieures, des moyens de fixation 6 dont l'un est représenté à plus grande échelle à la Fig. 2.The uprights 3 of the end elements, which are conveniently constituted by hollow stainless steel tubes of rectangular section and closed at their ends, have on their facing faces, near their upper and lower ends, means for attachment 6, one of which is shown on a larger scale in FIG. 2.

Ces moyens de fixation comprennent chacun une ferrure 7 repliée de façon à délimiter un parallélépipède à peu près cubique ouvert à sa partie supérieure et fixé, par exemple soudé par une face latérale sur la face du montant 3 dirigée vers la face correspondante du montant opposé symétrique. Le cube délimité par la ferrure 7 dont la face supérieure est ouverte comporte dans l'une 8 de ses faces latérales adjacentes à la face supérieure une fente 9 s'étendant verticalement à partir de l'arête supérieure du cube 7 et se terminant à peu près au centre de la face 8.These fixing means each comprise a folded fitting 7 so as to delimit a roughly cubic parallelepiped open at its upper part and fixed, for example welded by a lateral face on the face of the upright 3 directed towards the corresponding face of the opposite symmetrical upright . The cube delimited by the fitting 7, the upper face of which is open, has in one of its side faces adjacent to the upper face a slot 9 extending vertically from the upper edge of the cube 7 and ending slightly near the center of face 8.

Dans sa face opposée à la face 8, le cube 7 comporte une ouverture 10 de forme semi-circulaire dont l'extrémité arrondie est tangente à la face inférieure du cube 7 et s'ouvrant dans l'arête supérieure de ce cube.In its face opposite to face 8, the cube 7 has an opening 10 of semi-circular shape, the rounded end of which is tangent to the underside of the cube 7 and opening in the upper edge of this cube.

Les moyens de fixation 6 sont disposés sur chaque montant 3 en étant orientés dans le même sens.The fixing means 6 are arranged on each upright 3 while being oriented in the same direction.

Les éléments d'extrémité 2 comportent enfin une roulette orientable 11 fixée à une extrémité de chaque montant 3 au-dessous d'un dispositif de fixation 6, à l'opposé de sa face ouverte. En d'autres termes, les faces supérieures ouvertes des moyens de fixation sont orientées vers le haut.The end elements 2 finally comprise an orientable roller 11 fixed to one end of each upright 3 below a fixing device 6, opposite its open face. In other words, the open upper faces of the fastening means are oriented upwards.

Deux éléments d'extrémité 2 identiques sont disposés face à face et reliés ensemble au moyen de quatre entretoises identiques 12 reliant chacune les moyens de fixation 6 correspondant de deux éléments d'extrémité opposée.Two identical end elements 2 are arranged face to face and connected together by means of four identical spacers 12 each connecting the corresponding fixing means 6 of two opposite end elements.

Chaque entretoise 12 est constituée par une barre qui est par exemple en acier inoxydable, de section avantageusement cylindrique dont le diamètre est égal à la largeur de l'ouverture 10 de chaque moyen de fixation 6. Chaque entretoise 12 est fermée à son extrémité et comporte une tige axiale centrale 13 filetée en saillie vers l'extérieur sur laquelle est vissé un disque 14 ayant de préférence un diamètre supérieur à celui de la barre 12 et également de préférence en acier inoxydable.Each spacer 12 is constituted by a bar which is for example made of stainless steel, of advantageously cylindrical section whose diameter is equal to the width of the opening 10 of each fixing means 6. Each spacer 12 is closed at its end and has a central axial rod 13 threaded in outwardly projecting onto which is screwed a disc 14 preferably having a diameter greater than that of the bar 12 and also preferably made of stainless steel.

Comme on l'a représenté à la Fig. 2, la barre constituant chaque entretoise 12 est disposée avec ses extrémités introduites respectivement dans une ouverture 10 de chaque ferrure cubique 7 avec sa tige filetée 13 disposée dans la fente 9 et faisant saillie à l'extérieur de la paroi 8, le disque 14 formant poignée étant disposé à l'extérieur de la paroi 8. On comprend que l'extrémité de chaque entretoise se trouve alors disposée contre la face interne de la paroi 8. Les entretoises 12 étant maintenues sans jeu dans les ferrures 7 il suffit de serrer chaque poignée 14 pour obtenir un assemblage parfaitement rigide des deux éléments d'extrémité 2 du chariot 1 de façon extrêmement simple et rapide, sans aucun outil et par des moyens simples, mettant ainsi le montage des chariots 1 à la portée d'une infirmière ou d'une assistante, même sans aucune connaissance ni force physique particulière, un serrage suffisant étant assuré sans effort par un filetage des tiges 13 ayant un pas approprié.As shown in FIG. 2, the bar constituting each spacer 12 is disposed with its ends introduced respectively into an opening 10 of each cubic fitting 7 with its threaded rod 13 disposed in the slot 9 and projecting outside the wall 8, the disc 14 forming handle being disposed outside the wall 8. It is understood that the end of each spacer is then disposed against the internal face of the wall 8. The spacers 12 being held without play in the fittings 7 it suffices to tighten each handle 14 to obtain a perfectly rigid assembly of the two end elements 2 of the carriage 1 in an extremely simple and rapid manner, without any tool and by simple means, thus putting the assembly of the carriages 1 within the reach of a nurse or 'An assistant, even without any knowledge or particular physical strength, sufficient tightening being provided effortlessly by threading the rods 13 having an appropriate pitch.

Chacune des traverses 4 reliant ensemble deux montants 3 est constituée avantageusement par une glissière fixée sur les montants 3 de façon à présenter deux ailes horizontales s'étendant par rapport aux ferrures 7 du même côté que les ouvertures 10 de celles-ci. Les extrémités 15 de chaque glissière 4 sont légèrement relevées et repliées vers l'extérieur comme on le voit à la Fig. 1 de façon à délimiter entre elles une partie horizontale rectiligne 16 parallèle au plan contenant les extrémités 15 et légèrement espacées de ce plan.Each of the crosspieces 4 connecting together two uprights 3 advantageously consists of a slide fastened to the uprights 3 so as to have two horizontal wings extending relative to the fittings 7 on the same side as the openings 10 thereof. The ends 15 of each slide 4 are slightly raised and folded outwards as seen in FIG. 1 so as to delimit between them a rectilinear horizontal part 16 parallel to the plane containing the ends 15 and slightly spaced from this plane.

Les parties 16 horizontales des traverses 4 qui se font face vers l'intérieur constituent des supports adaptés pour recevoir les paniers 5.The horizontal parts 16 of the crosspieces 4 which face inward constitute supports adapted to receive the baskets 5.

Chaque panier 5. est constitué par une grille en fil d'acier inoxydable ayant deux parties horizontales d'extrémité 17 formant poignée, la largeur de chaque panier, et également de chacune de ses poignées 17, étant égale à la longueur de la partie horizontale 16 de chaque traverse 4, entre les extrémités 15 de celle-ci, la longueur de chaque panier 5 étant à peu près égale à la distance entre les éléments d'extrémité 2, déterminés par la longueur des entretoises 12.Each basket 5. is constituted by a grid of stainless steel wire having two horizontal end portions 17 forming a handle, the width of each basket, and also of each of its handles 17, being equal to the length of the horizontal part. 16 of each crosspiece 4, between the ends 15 of the latter, the length of each basket 5 being approximately equal to the distance between the end elements 2, determined by the length of the spacers 12.

On comprend que grâce à cet agencement, il est facile d'introduire horizontalement un panier 5 dans un chariot 1 monté de façon que ses poignées 17 se trouvent soutenues par les parties 16 des traverses 4, les extrémités des poignées 17 étant arrêtées par les extrémités 15 formant butées, en saillie vers le haut. Le panier se trouvant en place peut être facilement retiré en le soulevant légèrement pour échapper aux butées d'extrémité 15, d'un côté ou de l'autre du chariot tout en étant parfaitement maintenu sans risque de tomber ou de glisser lorsque le chariot est déplacé sur ses roulettes, ou lorsqu'un panier est partiellement tiré, comme un tiroir.We understand that thanks to this arrangement, it is easy to introduce horizontally a basket 5 into a carriage 1 mounted so that its handles 17 are supported by the parts 16 of the crosspieces 4, the ends of the handles 17 being stopped by the ends 15 forming stops, projecting upwards. The basket in place can be easily removed by lifting it slightly to escape the end stops 15, on one side or the other of the carriage while being perfectly maintained without risk of falling or slipping when the carriage is moved on its wheels, or when a basket is partially pulled, such as a drawer.

De préférence certaines des roulettes orientables 11 comportent un dispositif de freinage pouvant être actionné au pied (non représenté) d'un type connu classique.Preferably some of the swivel casters 11 comprise a braking device which can be actuated by foot (not shown) of a conventional known type.

Chaque chariot est enfin complété par un plateau P de forme rectangulaire également en acier inoxydable, présentant une forme légèrement creuse et reposant sur les deux entretoises 12 supérieures, qui le maintiennent entre elles et entre les extrémités supérieures des montants 3.Each carriage is finally completed by a tray P of rectangular shape also made of stainless steel, having a slightly hollow shape and resting on the two upper spacers 12, which hold it between them and between the upper ends of the uprights 3.

Les moyens de fixation 6 voisins des roulettes 11 sont situés à une distance suffisante au-dessus de celles-ci pour permettre d'amener le chariot au-dessus de la partie inférieure d'un dispositif de montage ou de démontage désigné dans son ensemble par la référence 20 à la Fig. 3.The fastening means 6 adjacent to the rollers 11 are located at a sufficient distance above them to allow the carriage to be brought above the lower part of an assembly or disassembly device designated as a whole by reference 20 in FIG. 3.

Le dispositif de montage 20 comprend un plateau 21 de forme à peu près rectangulaire monté sur quatre roulettes orientables 22 et est pourvu latéralement d'au moins deux vérins à vis 23 d'immobilisation.The mounting device 20 comprises a plate 21 of roughly rectangular shape mounted on four orientable rollers 22 and is provided laterally with at least two immobilizing screw jacks 23.

Sur l'un de ses côtés, le plateau 21 comporte deux montants verticaux parallèles 24 espacés sur les extrémités desquels est fixée une traverse horizontale supérieure 25 dont la longueur est égale à la longueur d'un chariot 1.On one of its sides, the plate 21 has two parallel vertical uprights 24 spaced at the ends of which is fixed an upper horizontal crosspiece 25 whose length is equal to the length of a carriage 1.

Une seconde traverse horizontale 26 d'une longueur égale à la traverse 25 est fixée parallèlement entre la traverse 25 et le plateau 21.A second horizontal crosspiece 26 with a length equal to the crosspiece 25 is fixed parallel between the crosspiece 25 and the plate 21.

Des bras horizontaux 27 de même longueur sont fixés à angle droit aux extrémités des traverses 25 et 26 de façon à s'étendre parallèlement dans le même sens.Horizontal arms 27 of the same length are fixed at right angles to the ends of the crosspieces 25 and 26 so as to extend parallel in the same direction.

Les extrémités des bras 27 situées d'un même côté par rapport aux montants 24 sont reliées entre elles par des fers verticaux 28 de section en U disposés de façon que leurs ailes s'étendent parallèlement dans le même sens que les bras 27.The ends of the arms 27 situated on the same side with respect to the uprights 24 are connected together by vertical bars 28 of U-shaped section arranged so that their wings extend parallel in the same direction as the arms 27.

Un support 29 est fixé sur chaque extrémité de la traverse horizontale 25 et sur une partie du bras 27 correspondant, et un bras rabattable 30 est articulé par une extrémité au sommet de chaque support 29 au moyen d'un axe 31. A son extrémité opposée au support 29 chaque bras 30 comporte un organe de retenue 32 constitué par un élément creux présentant en section une forme rectangulaire, ouvert vers le bas et dont la section est un peu supérieure à celle d'un montant 3 du chariot 1.A support 29 is fixed on each end of the horizontal crosspiece 25 and on a part of the corresponding arm 27, and a folding arm 30 is articulated by one end at the top of each support 29 by means of a pin 31. At its opposite end at the support 29 each arm 30 comprises a retaining member 32 constituted by a hollow element having in section a rectangular shape, open at the bottom and whose section is a little greater than that of an upright 3 of the carriage 1.

D'une façon avantageuse le dispositif 20 est entièrement réalisé en acier inoxydable et ses roulettes orientables comportent un dispositif de freinage.Advantageously, the device 20 is entirely made of stainless steel and its swivel casters include a braking device.

Ce dispositif permet de montier facilement un chariot tel que décrit plus haut: on dispose deux éléments d'extrémité 2 face à face verticalement en introduisant un montant 3 dans chacune des ferrures verticales 28 de section en U, et on rabat le bras 30 correspondant de façon que l'organe de retenue 32 vienne coiffer l'extrémité supérieure du montant 3 opposé à celui maintenu dans la ferrure 28. Les deux éléments d'extrémité 2 se trouvent ainsi maintenus face à face verticalement à la distance voulue l'un de l'autre. On dispose alors les entretoises supérieures 12 en place dans les dispositifs de fixation 6 en les faisant passer au-dessous des bras 30 et en serrant simultanément avec chaque main les poignées d'extrémité 14 des entretoises. On dispose ensuite de la même façon les entretoises inférieures 12 en les faisant passer entre la traverse inférieure 4 et le plateau 21 du dispositif 20, le chariot 1 se trouvant ainsi complètement monté et on le libère en relevant les bras 30.This device makes it possible to easily mount a carriage as described above: there are two end elements 2 facing each other vertically by introducing an upright 3 into each of the vertical fittings 28 of U-shaped section, and the corresponding arm 30 is folded down. so that the retaining member 32 comes to cap the upper end of the upright 3 opposite to that held in the fitting 28. The two end elements 2 are thus held face to face vertically at the desired distance from one another. The upper spacers 12 are then placed in place in the fixing devices 6 by passing them under the arms 30 and by simultaneously tightening with each hand the end handles 14 of the spacers. The lower spacers 12 are then arranged in the same way by passing them between the lower crosspiece 4 and the plate 21 of the device 20, the carriage 1 thus being completely assembled and it is released by raising the arms 30.

On comprend que cette opération extrêmement simple et rapide peut être effectuée facilement par un personnel non qualifié.It is understood that this extremely simple and rapid operation can be carried out easily by unqualified personnel.

Pour démonter un chariot on effectue les mêmes opérations en sens inverse.To dismantle a carriage, the same operations are carried out in reverse.

Lorsqu'un chariot est démonté les six éléments qui le constituent, savoir les deux éléments d'extrémité 2 et les quatre entretoises 12 peuvent être disposés sur un porte-chariots déplaçable désigné dans son ensemble par la référence 33 à la Fig. 4.When a carriage is dismantled, the six elements which constitute it, namely the two end elements 2 and the four spacers 12, can be arranged on a movable carriage carrier designated as a whole by the reference 33 in FIG. 4.

Le porte-chariots 33 comprend des moyens pour suspendre et retenir les éléments de plusieurs chariots démontés.The carriage holder 33 comprises means for suspending and retaining the elements of several disassembled carriages.

Ces moyens comprennent un bâti constitué par un cadre inférieur rectangulaire comportant deux longerons 34 reliés par quatre traverses 35. Ce cadre inférieur comporte à ses extrémités deux montants verticaux parallèles 36 réunis à leur extrémité supérieure par une traverse 35'.These means comprise a frame constituted by a rectangular lower frame comprising two longitudinal members 34 connected by four crosspieces 35. This lower frame comprises at its ends two parallel vertical uprights 36 joined at their upper end by a crosspiece 35 '.

Les milieux des traverses 35" sont reliés entre eux par un longeron 34' soutenu par deux montants intermédiaires 36' et portant deux paires espacées de bras horizontaux parallèles transversaux 37.The midpoints of the crosspieces 35 "are interconnected by a beam 34 'supported by two intermediate uprights 36' and carrying two spaced pairs of parallel transverse horizontal arms 37.

Les bras 37 de chaque paire sont espacés d'une distance un peu inférieure à la longueur des traverses 4 des éléments d'extrémité 2 des chariots.The arms 37 of each pair are spaced a distance slightly less than the length of the crosspieces 4 of the end elements 2 of the carriages.

Le porte-chariots, déplaçable 33 comprend en outre à chaque extrémité un râtelier constitué par une bande de métal crénelée 38 fixée horizontalement sur la partie supérieure de chaque traverse 35' de façon que les pattes délimitant les créneaux s'étendent horizontalement vers l'extérieur.The movable carriage carrier 33 further comprises at each end a rack consisting of a crenellated metal strip 38 fixed horizontally on the upper part of each cross 35 'so that the tabs delimiting the slots extend horizontally outward .

Le porte-chariots comprend enfin des moyens de retenue verticaux 39 constitués par des tiges de métal recourbées en U fixées verticalement et parallèles par les extrémités de leurs branches dans une partie intermédiaire de la longueur des longerons 34, des tiges transversales 39' étant disposées entre les extrémités de chaque tige 39.The carriage carrier finally comprises vertical retaining means 39 constituted by metal rods curved in a U fixed vertically and parallel by the ends of their branches in an intermediate part of the length of the longitudinal members 34, transverse rods 39 'being arranged between the ends of each rod 39.

Le porte-chariots 33 comme le chariot 1 est entièrement réalisé en éléments d'acier inoxydable et comporte aux angles de son cadre inférieur des roulettes orientables 40 qui sont également de façon avantageuse du type muni d'un frein.The trolley carrier 33 like the trolley 1 is entirely made of stainless steel elements and comprises at the corners of its lower frame orientable rollers 40 which are also advantageously of the type provided with a brake.

Le porte-chariots déplaçable 33 est destiné à ranger et à porter avec le plus faible encombrement possible des éléments d'un certain nombre de chariots.The movable trolley holder 33 is intended to store and carry with the smallest possible dimensions of the elements of a number of trolleys.

Les éléments d'extrémité 2 des chariots sont suspendus sur les paires de bras 37 de part et d'autre du longeron 34' sur lesquels ils sont soutenus par la traverse supérieure 4 de chaque élément, les entretoises 12 sont suspendues verticalement aux râteliers 38 dans les créneaux desquels sont introduites les tiges filetées 13, les poignées 14 étant serrées pour les maintenir en place.The end elements 2 of the carriages are suspended on the pairs of arms 37 on either side of the beam 34 'on which they are supported by the upper cross member 4 of each element, the spacers 12 are suspended vertically from the racks 38 in the slots of which the threaded rods 13 are introduced, the handles 14 being tightened to hold them in place.

Les plateaux supérieurs amovibles P des chariots sont disposés verticalement entre les organes de retenue 39.The removable upper plates P of the carriages are arranged vertically between the retaining members 39.

On comprend que grâce à cet agencement un grand nombre de chariots démontés peut être disposé sur un seul porte-chariots 33.It will be understood that, thanks to this arrangement, a large number of disassembled carriages can be placed on a single carriage carrier 33.

Le dernier élément de l'équipement suivant l'invention est constitué par un support fixe désigné dans son ensemble par la référence 41 et représenté à la Fig. 5, destiné à être installé dans le stock stérile de l'installation qui sera décrite dans la suite.The last element of the equipment according to the invention consists of a fixed support designated as a whole by the reference 41 and shown in FIG. 5, intended to be installed in the sterile stock of the installation which will be described below.

Le support fixe 41 est simplement constitué de deux éléments d'extrémité verticaux parallèles 42 comportant des traverses horizontales parallèles 43 qui sont identiques aux montants 3 et aux traverses 4 des éléments d'extrémité 2 des chariots, et pouvant ainsi être fabriqués simultanément avec ceux-ci, deux montants 42 correspondants pouvant être fixés te long d'un mur par des moyens quelconques appropriés tels que des ferrures 45.The fixed support 41 is simply made up of two parallel vertical end elements 42 comprising parallel horizontal crosspieces 43 which are identical to the uprights 3 and to the crosspieces 4 of the end elements 2 of the carriages, and can thus be produced simultaneously with them. Ci, two corresponding uprights 42 which can be fixed along a wall by any suitable means such as fittings 45.

Les traverses 43 sont ainsi adaptées pour recevoir des paniers tels que les paniers 5 décrits plus haut disposés les uns au-dessus des autres avec un espacement 44 juste suffisant pour permettre l'introduction et le retrait des paniers individuellement.The crosspieces 43 are thus adapted to receive baskets such as the baskets 5 described above arranged one above the other with a spacing 44 just sufficient to allow the introduction and removal of the baskets individually.

Les supports fixes 41 sont destinés à être montés fixes dans le stock stérile dans lequel sont emmagasinés les paniers garnis de lots d'instruments comme indiqué plus haut en référence au procédé suivant l'invention.The fixed supports 41 are intended to be mounted fixed in the sterile stock in which the baskets filled with lots of instruments are stored as indicated above with reference to the process according to the invention.

En se référant maintenant à la Fig. 6 qui montre la séquence des différentes phases dans la mise en oeuvre du procédé suivant l'invention.Referring now to FIG. 6 which shows the sequence of the different phases in the implementation of the method according to the invention.

La zone I délimitée en traits pleins représente la zone dite "propre", c'est-à-dire stérile. Dans la phase 1 du procédé, on prélève dans une salle d'emmagasinage en stock stérile des éléments de chariots démontés disposés sur un porte-chariots déplaçable, on dispose dans la phase 2, les éléments de chariots sur un dispositif de montage (Fig. 4) et on assemble les différents éléments de chariots.Zone I delimited in solid lines represents the so-called "clean" zone, that is to say sterile. In phase 1 of the process, elements of dismantled trolleys placed on a movable trolley carrier are taken from a sterile storage room in sterile stock. In phase 2, the trolley elements are placed on a mounting device (Fig. 4) and the various elements of the carriages are assembled.

Dans la phase 3 on prélève dans des supports fixes (Fig. 6) montés dans la salle d'emmagasinage en stock stérile un certain nombre de paniers contenant chacun une partie des instruments, accessoires et autres, préalablement répertoriés, nécessaires pour un chirurgien pour effectuer une intervention donnée et, dans la phase 4, on charge ces paniers sur les chariots montés.In phase 3, a number of baskets each containing a portion are taken from fixed supports (Fig. 6) mounted in the storage room in sterile storage. instruments, accessories and others, previously listed, necessary for a surgeon to perform a given intervention and, in phase 4, these baskets are loaded onto the mounted carriages.

Dans la phase 5 du procédé on transporte ensuite ces chariots chargés en salles d'opérations. Le chirurgien effectue alors son intervention en se servant des instruments et des accessoires contenus dans les paniers en utilisant les chariots comme guéridons de service, dans la phase 6.In phase 5 of the process, these loaded trolleys are then transported to the operating rooms. The surgeon then performs his intervention using the instruments and accessories contained in the baskets using the carts as service pedestal tables, in phase 6.

Dans la phase 7 le personnel de salle sort les chariots de la salle d'opérations et les amène dans la stérilisation côté "sale" délimitée en traits mixtes et désignée à la Fig. 1 par la référence Il dans laquelle, dans la phase 8, on décharge les paniers des chariots, on dispose ces derniers dans un dispositif de démontage dans la phase 9 et on les démonte, en phase 10 on dispose ensuite les différents éléments des chariots sur un porte-chariots déplaçable adapté pour porter les éléments de plusieurs chariots démontés, et dans la phase 11 on procède au lavage des paniers ainsi que du matériel qu'ils contiennent et on reconditionne les lots d'instruments dans les paniers.In phase 7, the room personnel take the trolleys out of the operating room and bring them into sterilization on the "dirty" side delimited in phantom lines and designated in FIG. 1 by reference II in which, in phase 8, the baskets of the carriages are unloaded, these are placed in a dismantling device in phase 9 and they are dismantled, in phase 10 the various elements of the carriages are then placed on a movable trolley holder adapted to carry the elements of several dismantled trolleys, and in phase 11 the baskets and the material they contain are washed and the batches of instruments are reconditioned in the baskets.

On effectue la phase 12 dans une zone délimitée en traits interrompus à la Fig. 1 et désignée par la référence III qui représente un ensemble de désinfection et de stérilisation, phase dans laquelle on désinfecte les porte-chariots démontés et dans la phase 13 on stérilise les paniers et leur contenu.Phase 12 is carried out in an area delimited in broken lines in FIG. 1 and designated by the reference III which represents a set of disinfection and sterilization, phase in which the disassembled carriage carriers are disinfected and in phase 13 the baskets and their contents are sterilized.

Dans les deux dernières phases, 14 et 15 du procédé on emmagasine dans la phase 14 les paniers stériles sortant de l'ensemble de stérilisation dans la salle de stockage stérile et on les dispose dans les supports fixes prévus dans cette salle tandis que dans la phase 15 on emmagasine dans ladite salle de stockage les porte-chariots déplaçables portant les éléments de chariots désinfectés, à I sortie de l'ensemble de désinfection, prêts à être réutilisés dans une nouvelle séquence des phases du procédé.In the last two phases, 14 and 15 of the process, the sterile baskets leaving the sterilization assembly are stored in phase 14 in the sterile storage room and they are placed in the fixed supports provided in this room while in the phase 15 the movable trolley carriers carrying the disinfected trolley elements are stored in said storage room, at the outlet of the disinfection assembly, ready to be reused in a new sequence of the process phases.

On constate à l'énumération des différentes phases du procédé qu'à aucun moment il n'est nécessaire d'utiliser un matériel, des instruments ou des accessoires d'une provenance extérieure; la totalité du matériel nécessaire aux chirurgiens et à ses aides arrivant en salles d'opérations en provenant du stock stérile et ressortant en totalité de la salle d'opérations pour être reconditionné en vue d'une nouvelle opération.It is noted from the list of the different phases of the process that at no time is it necessary to use equipment, instruments or accessories from an outside source; all the equipment necessary for surgeons and their assistants arriving in operating rooms from the sterile stock and leaving the entire operating room to be reconditioned for a new operation.

Eri d'autres termes on comprend que grâce au procédé suivant l'invention la totalité du matériel nécessaire à un chirurgien et à ses aides pour effectuer une intervention donnée parcourt un circuit prévu dans une installation en transitant au cours d'une seule des phases (phase 6) du procédé par la salle d'opérations d'où elle ressort après l'opération pour revenir à son point de départ.In other words, we understand that thanks to the process according to the invention, all the equipment necessary for a surgeon and his assistants to perform a given intervention travels through a circuit provided in an installation, passing through during only one of the phases ( phase 6) of the process by the operating room from which it emerges after the operation to return to its starting point.

On décrira maintenant en référence à la Fig. 7 un schéma d'une installation pour une mode particulier de réalisation du procédé suivant l'invention.We will now describe with reference to FIG. 7 is a diagram of an installation for a particular embodiment of the method according to the invention.

En se référant à la Fig. 7 l'installation comprend une zone dite stérilisation côté "propre" ou stock stérile désignée par la référence et délimitée en traits pleins, une zone dite stérilisation côté "sale" désignée par la référence Il et délimitée en traits mixtes, et une zone intermédiaire III délimitée en traits interrompus et qui est constituée par un ensemble de désinfection et de stérilisation.Referring to FIG. 7 the installation comprises a so-called sterilization zone on the "clean" side or sterile stock designated by the reference and delimited in solid lines, a so-called sterilization zone on the "dirty" side designated by the reference II and delimited in broken lines, and an intermediate zone III delimited in broken lines and which consists of a set of disinfection and sterilization.

La zone propre I comprend un stock stérile 51 dans lequel est installé un poste 52 d'emmagasinage des éléments de chariots démontés et désinfectés, ce poste étant constitué par un porte-chariots déplaçable 33 décrit plus haut qui est disposé à l'emplacement le plus pratique dans le stock stérile 51, emplacement dans lequel il est immobilisé grâce au système de freinage de ses roulettes. Ce poste d'emmagasinage 52 est celui dans lequel sont prélevés des éléments de chariots dans la phase du procédé décrit plus haut.The clean zone I comprises a sterile stock 51 in which is installed a station 52 for storing disassembled and disinfected cart elements, this station being constituted by a movable cart carrier 33 described above which is arranged at the most convenient in sterile stock 51, location in which it is immobilized thanks to the braking system of its rollers. This storage station 52 is the one from which elements of the carriages are removed in the phase of the process described above.

Le stock stérile 51 comporte également un poste 53 de montage des chariots, constitué par un dispositif de montage 20 tel que décrit plus haut, immobilisé au moyen des dispositifs de freinage de ses roulettes, ce poste de montage 53 étant celui utilisé dans la phase 2 du procédé précité.The sterile stock 51 also includes a station 53 for mounting the carriages, constituted by a mounting device 20 as described above, immobilized by means of the braking devices of its rollers, this mounting station 53 being that used in phase 2 of the above process.

Il est en outre prévu dans le stock 51 au moins un poste 54 de stockage des paniers garnis de leurs lots d'instrumentation répertoriés stérilisés, ce poste étant constitué par au moins un support fixe tel que le support 41 décrit plus haut. Ce poste 54 est celui utilisé dans la phase III du procédé.There is also provided in the stock 51 at least one station 54 for storing baskets filled with their instrumentation batches listed sterilized, this station being constituted by at least one fixed support such as the support 41 described above. This item 54 is that used in phase III of the process.

La salle 51 peut s'ouvrir sur un couloir 55 desservant par exemple deux salles d'opérations 56a et 56b par l'intermédiaire des locaux habituels utilisés pour la préparation du chirurgien et de ses assistants et d'une chambre d'anesthésie suivant un agencement classique ne faisant point partie de l'invention.Room 51 can open onto a corridor 55 serving for example two operating rooms 56a and 56b via the usual premises used for the preparation of the surgeon and his assistants and an anesthesia chamber according to an arrangement classic not part of the invention.

Les salles d'opérations comprennent des portes de sortie qui débouchent sur un couloir 57 qui fait partie de la zone dite sale, ce couloir conduisant à l'entrée 58 de la zone III constituée par l'ensemble de désinfection et de stérilisation.The operating rooms include exit doors which lead to a corridor 57 which is part of the so-called dirty zone, this corridor leading to the entrance 58 of zone III constituted by the disinfection and sterilization assembly.

Il est prévu dans le couloir 57 au voisinage de l'entrée 58 de la zone III un poste 59 de démontage des chariots, constitué par un dispositif tel que le dispositif 20, immobilisé au moyen des systèmes de freinage de ses roulettes au voisinage d'un poste de lavage 60, ce poste 59 de démontage des chariots étant celui qui est utilisé pour la phase 9 du procédé décrit plus haut, et qui est également utilisé avantageusement pour la phase 8 de ce procédé, il est en effet logique d'amener directement le chariot monté au poste de démontage avant de décharger les paniers comme prévu dans la phase 8 du procédé.There is provided in the corridor 57 in the vicinity of the entrance 58 of zone III a station 59 for dismantling the carriages, constituted by a device such as the device 20, immobilized by means of the braking systems of its rollers in the vicinity of a washing station 60, this station 59 for dismantling the carriages being that which is used for phase 9 of the process described above, and which is also advantageously used for phase 8 of this process, it is indeed logical to bring directly the cart mounted at the dismantling station before unloading the baskets as planned in phase 8 of the process.

Il est également prévu à l'extrémité du couloir un poste 61 de chargement des éléments de chariots démontés, ce poste 61 étant constitué par un porte-chariots déplaçable 33 immobilisé par freinage de ses roulettes au voisinage de l'entrée 58 de l'ensemble de désinfection et de stérilisation. Ce poste 61 est celui utilisé pour la phase 10 du procédé.There is also provided at the end of the corridor a station 61 for loading the elements of dismantled carriages, this station 61 being constituted by a movable carriage carrier 33 immobilized by braking its rollers in the vicinity of the entrance 58 of the assembly disinfection and sterilization. This station 61 is the one used for phase 10 of the process.

Le poste de lavage 60 n'est mentionné qu'à titre indicatif, ce poste existant déjà en un point ou un autre d'un bloc opératoire quelconque au voisinage de l'ensemble de désinfection et de stérilisation, qui est également classique. On notera cependant que ce poste de lavage et cette installation de désinfection bien que ne faisant pas partie de l'invention s'inscrivent cependant tout naturellement dans le procédé de traitement de matériels chirurgicaux suivant l'invention et trouvent bien entendu leur place dans l'installation pour la mise en oeuvre de ce procédé.The washing station 60 is only mentioned for information, this station already existing at one point or another in any operating room in the vicinity of the disinfection and sterilization assembly, which is also conventional. It should be noted, however, that this washing station and this disinfection installation, although not forming part of the invention, are however quite naturally part of the process for treating surgical materials according to the invention and naturally find their place in the installation for the implementation of this process.

On notera toutefois que l'ensemble de désinfection et de stérilisation constituant la zone III doit être prévu de manière à pouvoir recevoir au moins un porte-chariots déplaçable 33 tel que décrit plus haut portant les éléments de plusieurs chariots démontés pour y être désinfectés.Note however that the disinfection and sterilization assembly constituting zone III must be provided so as to be able to receive at least one movable carriage carrier 33 as described above carrying the elements of several disassembled carriages to be disinfected therein.

Le poste de lavage 60 est utilisé normalement pour l'exécution de la phase 11 du procédé, tandis que l'ensemble de désinfection et de stérilisation de la zone III est utilisé pour l'exécution des phases 12 de désinfection du porte-chariots déplaçable portant les éléments de chariots démontés et de la phase 13 de stérilisation des paniers reconditionnés.The washing station 60 is used normally for the execution of phase 11 of the process, while the disinfection and sterilization assembly of zone III is used for the execution of the phases 12 of disinfection of the movable carriage carrier carrying elements of dismantled carts and phase 13 of sterilization of reconditioned baskets.

La phase 14 du procédé, c'est-à-dire l'emmagasinage des paniers stériles avec des lots d'instrumentation et d'accessoires qu'ils contiennent est effectué au sortie de l'ensemble de stérilisation de la zone III, au poste 54 d'emmagasinage déjà utilisé lors de la phase 3, tandis que la phase 15 d'emmagasinage des chariots est effectuée au poste 52 d'emmagasinage utilisé dans la phase 1. On comprend en effet que les porte-chariots déplaçables portant les éléments de chariots démontés doivent être déplacés de temps à autre. En effet lorsqu'un porte-chariots 33 se trouvant au poste 53 de montage a été entièrement dégarni des éléments qu'il portait il convient de le remener dans la zone sale II, au poste 61 pour remplacer celui qui a été complètement chargé d'éléments de chariots et qui est passé dans la salle 51 par l'intermédiaire de la zone III dans laquelle il a été désinfecté. Ce transfert peut être effectué soit entre deux interventions en traversant l'une des salles d'opérations 56A ou 56B pour être ramené par le couloir 57, soit encore en lui faisant traverse l'ensemble de désinfection en sens inverse.Phase 14 of the process, that is to say the storage of sterile baskets with batches of instrumentation and accessories that they contain is carried out at the exit of the sterilization unit of zone III, at the post 54 of storage already used during phase 3, while phase 15 of storage of the carriages is carried out at the storage station 52 used in phase 1. It is in fact understood that the movable carriages carrying the elements of dismantled carts should be moved from time to time. In fact, when a trolley carrier 33 located at the mounting station 53 has been completely stripped of the elements it was carrying, it should be brought back into the dirty zone II, at station 61 to replace the one which has been fully loaded with elements of trolleys and which passed into room 51 via zone III in which it was disinfected. This transfer can be carried out either between two interventions by crossing one of the operating rooms 56A or 56B to be brought back by the corridor 57, or even by making it pass through the disinfection assembly in the opposite direction.

Il ressort de ce qui précède que l'équipement et le procédé pour la mise en oeuvre de cet équipement suivant l'invention permettent un traitement rationnel de l'instrumentation avec un matériel d'une utilisation extrêmement simple et présentant toute facilités en ce qui concerne les possibilités de désinfection et de stérilisation. Grâce à l'invention il est désormais possible de réaliser des salles d'opération à murs parfaitement lisses et dépourvus de toutes solutions de continuité ou de matériels encastrés dont l'installation est coûteuse, les salles d'opérations ainsi réalisées de façon simple et économique pouvant être désinfectées et stérilisées dans leur totalité sans la moindre difficulté tout en abaissant considérablement les frais d'installation des blocs opératoires.It appears from the foregoing that the equipment and the method for implementing this equipment according to the invention allow rational treatment of the instrumentation with equipment of extremely simple use and having all facilities with regard to the possibilities of disinfection and sterilization. Thanks to the invention it is now possible to produce operating rooms with perfectly smooth walls and devoid of any continuity solutions or built-in equipment whose installation is expensive, the operating rooms thus produced in a simple and economical manner. can be disinfected and sterilized in their entirety without the slightest difficulty while considerably reducing the costs of installing operating theaters.
